问题如下：
点击“增加”按钮，增加了一行，但是点击“测试”按钮，显示HTML内容，发现新增的select没有name属性，se1.setAttribute("name","cp"+cpno.toString());语句执行没出错，如果在这一行语句下执行alert(se1.name)，显示的结果没错，可是点击“选择”按钮，则出错，说document.forms(0).cp2.options为空或不是对象，我认为就是name属性的问题。可是为什么name属性会没有赋制值呢？se1.setAttribute("name","cp"+cpno.toString());语句没用吗？
请各位高手指点一下，谢谢！
